Abstract
The effects of sorbitol and monosodium glutamate upon survival during storage of
freeze-dried Lactobacillus bulgaricus, Lactobacillus plantarum,
Lactobacillus rhamnosus, Enterococcus durans and Enterococcus faecalis
were examined. There were no significant differences in survival during freeze-drying
after addition of sorbitol or monosodium glutamate. However, these compounds were found
to increase the stability of most strains during long-term storage. Various survival
patterns were observed among the strains considered. However, for most of them,
both compounds were proven effective in maintaining high degrees of viability over long
periods of storage.
